Seneca, De Brevitate Vitae 1.1

“We don’t have too little time, but we do waste most of it. Life is long enough for the completion of the greatest affairs—it is apportioned to us generously, if it is wholly well managed.”

 

non exiguum temporis habemus, sed multum perdidimus. satis longa uita et in maximarum rerum consummationem: large data est, si tota bene conlocaretur.
